Having already become the first Bills rookie linebacker to record an interception in three consecutive games, Kiko Alonso sealed the victory with a diving pick as Flacco was driving the Ravens down the field for a potential game-tying field-goal attempt with one minute remaining.

The Bills dominated the line of scrimmage, rushing 55 times for 203 yards while the Ravens managed just 24 yards on nine carries.

Although Flacco's lack of weapons beyond wide receiver Torrey Smith has been the Ravens' bugaboo over the first month, the offensive line's ineptitude shouldn't go unnoticed. The tackles have struggled to open running lanes while the interior has been a sieve against the pass rush.

With the Ravens abandoning the run, Smith almost single-handedly kept them in the game with 166 yards and a second-half touchdown. Unless Smith finds a reliable sidekick, the defending Super Bowl champions are in for a long season on offense.

Here's what else we learned:

1. The Bills' rookie class put on a show. In addition to Alonso's twointerceptions, wide receiver Robert Woods totaled 93 yards and one touchdown on five touches. He had a second score that was overturned on replay. EJ Manuel completed just 10 passes, but he led the Bills on scoring drives when they absolutely had to respond.

2. Flacco can't throw to Ed Dickson because the tight end already has six drops this season. Flacco couldn't throw to Brandon Stokley because the slot receiver was inactive. As a result, Tandon Doss and Dallas Clark combined for 18 targets. Clark was on his couch when the preseason started. Doss couldn't last through final cuts. The Ravens desperately need Marlon Brown and Deonte Thompson to gain Flacco's full trust.
